Ceramic bearing steel bearing, compared with the advantage is:1, speed higher than steel, ceramics, can reduce operating in the same precision and the centrifugal force, improve speed.2, high precision occasions: ceramic hardness and young modulus is higher than that of the steel, the same load, the smaller, thus mechanical deformation can be applied to more precise.Three, use longer than that of the steel bearing, the highest prolonged five times

Ceramic Ball Bearings Ceramic Ball Bearings The hybrid ceramic ball bearing features bearing rings made of bearing steel (Gcr15) or stainless steel (9cr18). The ceramic ball bearing is mainly made of silicon nitride (Si3N4), rconia (ZrO2) or alumina (Al2O3), among which Si3N4 is of excellent overall erformance and has become the preferred material for ceramic ball bearing. The density of Si3N4 ceramic is 3.20g/cm3, much lower than that of bearing steel (7.85g/cm3).
